VTo all whom #may concern:

Be it known that I, JOSEPH OPPMAN, af citizen ofthe United States, residingat Connellsville, in the county or' Fayette and Stat-e ot Pennsylvania., have invented certainnew and useful improvements in Faper Fasting and Severing` Machines, of Which the following is a specication. l V Q i This invention relates toapparatus i'or applying paste 'to Webs or rollsV ot pap`er,.di' viding the pasted Websfinto strips ot any required Width, and severing the pasted .and divi ded strips into predetermined lengths, and has 'for one ot its objects to simplify and improve the construction and increase the efiicieney and utilityof devcesof this character.

Another object of the invention is topro. Vvide a device of this'character which may be adapted to Webs or rolls of paper of varyf ing Widths and lengths, and to apply paste uniformly to the Whole Web and divide the same into strips of varying Widths, and sev' ering the pasted and divided strips intoY predetermined lengths.

lVitli these and other objects in view, the invention consists in certain novel features oi construction as hereinafter shown and described and then specifically pointed out in the claims and in the drawing-s illustrative of the preferred embodiment ot the invention;

. Figure 1 is an end elevatiomand Fig. 2 is a plan vienT of the improved ap'- paratus.

The improved apparatus is designed more particularly; for Aapplying paste Vto a Vivob or roll of paper, for instance'vvall paper, dividing the pasted lweb in'strips of predetermined Widths and severing the pasted'and divided strips in predetermined lengths.

The improved apparatuscomprises Va 'supe porting structure including end lmembers 10, of relatively heavy material, preferably Yot Wood. Supported between the end mem'- bers 1'O is 'a trough member, preferably of sheet metal and indicated at 11 having one side `about inV line with the center or" the trough as indicated at 12 and the other side extending upwardly asindicated at 13.

i Extending between theend members 10 is an L-shaped member indicatedat 14, preterably oi" sheet metal, and coacting with the upwardly exten'dingside 13 ofthe trough to form a tankor reservoir for paste.

`The side 13 'of the troughalso forms one Y wall of lthe tank, the latter underlying `a portion of the trough as indicated at 15.

A stay member 16 is disposed beneath the trough to support the same.

- Mounted for rotation in the trough 11 is a drum comprising acylindrical body portion 17, and closed ends, one of which is indicated at v18 in Fig. 1, and kdisposed in the end mem? bers 1() are pins, one of Which is indicated at 19.

By this means 4the drum is mountedl for rotationon the endmember-s 11A and isthere'- Ytor rotative 'in the trough. The barrel or body 17 of the drum is concentric to the Y curved portion or the trough and only slightly smaller than the same, so that a thin iilm of the paste ivill flow into this thin space and be spread uniformly over the barrel of the drinn as the latter vis rotated, as hereafter ex lained. Y t

intending between the end membors'lO is a guide roller 2O having journals, one of which is indicated at 21 and including .a threaded end 22engaging in the roller 20.

a wear sleeve, one of which is represented at 23, in Fig. in the end memberslO.' i y One of the pins 21 isprovided ivithpa triction disk 24 operating externally of the adjacent endmember 10, as shown.

The rollerQO is 'preferably located above 'the center of the drum 17, as shown in Figs.

vThe body of each of the pins21 engages in V y i Formed inv the .confronting faces' or' the end members 10 are'horizontal'guidevvays A28 to receive the ends: ot a rod 29 designed tolsuppo'rt; a roll of paper indicated 313730,

.the rodloeingg reta-ined in place by hooks 29".

The end of the web of paper 3l is passed between the barrel 17 of the drumandthe bearing,v roller;- 27Y and: thence between the-y barrelfi'l" of thedrum andthe guide rol-lerl 2O and thence urawn upwardly, the pulling upwardly of 'the Webofpaper causing ther drum to be rotated and carry `athin film of past-e with it'and apply it' uniformly upon the paper as itis drawn over the druin and held inconta'et therewith bythe gravity of VtheV bearing roller 27.

this means `the requisite vam'oimt of paste is uniformly and evenly' applied' to' 'the paper as it is drawn upwardly, and the paper heldin Contact With the drum by the Weight of thebearing'v roller with s ufiicient tension to linsu-re the proper 'action'.I

Bearing upon each of the end members l0 transverse slots `39 to receive-'ciampiscrews n 40, to enable the blade to be adjusted rela tive to" its backing member 38. Slidably dispgosed atvits ends in the Af uideways formed by the coactinp; n-ienibers 32 and 35, is a `backing'member l Otani-ther blade 42 having; transverse .slots indicated at t3-to rereiye olanip screws lir, andprovidingineans for the adjustment ofthe blade 4t2 relative to the backing member di and ythe stationary blade 37.

The members 35 are provided respectively with longitudinal slot-s d25,7and rising from the infeinber l-lA and extending' thrt'iugh the slotsk are studs 46, andirisin-g respectively from the members at the end nearest to therstationa-ry bl-:ide 3,7 are studs 47, and connectingrthe studs li6 and i7 at each side of the device is apull string` d8. p The springs 41S opera te to drawvthe movable blade i2l audits bacliiigfV member -l toward the stationary blade and cause the blades to coact as hereafter explained;v

drawn' outwardly against the `resistance et" ioo CJi

4 wardly above the severing knife 37, and

the springs 48, to cause the sockets 76 to be is disengaged' from the wheel 24.'

lWith an apparatus thus described, the operation is as follows:

A roll of paper to be treated, for instance? a roll of wall paper with the edges un'-V trimmed, is disposed on the rod 29 and the free end passed over the drum 17 beneath the rollers 27 and 2() and' over the roller 50, the bracket 53 havingrbeen previously re-` leased by loosening the clamp nut 8l by which the cutter 54 is held inrinoperative position and turned back out of the way.

The bracket 53 is then returned to operative position with its cutting wheel vin engageinent with the paper asit passes over the roller 50.

The valve, not shown, which controls the flow of paste from the tank is then opened, and as the paper 31 is drawn upward, the drum 17 is rotated by the friction of the paper and carries a thin i'ilm of paste with it and applies it uniformly to the paper as it passes between and' over the several. rollers, the cutting wheel 54 at the same time dividing the web of paper longitudinally. Y

Vilhen employed for pasting and trimming' wall paper, the bracket will be adjusted to cut the imprinted edge from the paper. and if both edges are to be trimmed, two of the brackets withrthe cuttingrblades will be employed, as is obvious. As the pasted' and divided web is drawn upwardly it imparts motion'to the roller 20 :iiid thence to the friction disk 24, the friction pinion 65, the shaft 64` worm pinion 70, worin lrear 69 and its arms 72.

By adjusting the friction pinion 65 in tho slot or guideway in the member 57` the speed maj,7 be readily controlled to correspondingly control the iovements of the arm 72 and cause the extension 73 of the latter to trip the pawls 78. 79 once during' each revolution of the wheel 69 and thus release the member 4l. and its blade 42 and permit the springs 48 to move the blade-against the pasted and divided paper and coact with the blade 37 to sever it transversely.

The speed of the wheel 69 may thus be controlled to correspondingly control the length of the paper which is draw/n upwhen this length is reached, the member 72 will release the movable blade, described.

rllhe upper face of the member 57 is profl v vided with graduations, indicated at 82, to enable the pinion 65 to be accurately set, to

correspond tothe required lengths of the webs or strips.

The preferred embodiment of the invenas before tion is disclosed in the drawings and set forth in the specification, but it `will be understood that modifications-within the scope of the claimed invention maybe inadein the `construction' without departing' from the principle of the invention or -sacrin'icinfr any of its advantages. i
